I've done a few searches and come up with nothing. I've mostly been shooting pistols lately due to how far I have to drive to shoot my AR. Finally I have found a place to shoot only 45 minutes from my house, I have rediscovered how bad the stock trigger is on my M&P 15. What is a good trigger for this rifle. I have seen after market triggers for $200 +. I have also had people tell me to take it to a gunsmith for polishing. I wish I had more experience.
